Sweeper.



Application ,ef 52m u r- Be it known that Aurelio i a subject of theKing of [rl'vve in the City et' New York, lnoroufg l liattan. and countyet New You." 1New York, have invented certain usefulmprovemeuts inSweeper-s, the following a full, cle :nifl scription, which will enablein the art to which it pertai. s t use the Same, reeence lbeiu;Daccompanying drawings, and to of reference maxlicfi tliereer., vfhiclpart of this specification.

The object of my invention is e svv'eeping device 'Wlflicli willeiectualljr remove and. collect dust and dirt, and which is of simpleconstruction, easy of manipulation, and of low cost of manufacture.

make use of a casing provided. with dust pau and adapted to glide overthe surface to be cleaned, and e revoluble 'e-ru actuated solely byengagement of its uri 3 with said surface aud So mounted within saidcasing that its exis ol rotation is immovable relatively to the edge ofthe dust pau, which is immediat-ely .f'tcljaeeiit the brush. By thisarrangement, 'when pressure is applied by hand te the loaei of tlmcamu-Y. such pressure performs two distinct to wit, (l) yit muses tiresai eflge of the lust pan to img tightly against the surlv: to becleaned, and (2) it increases the c of lexure of the brush bri es, anddoing; renders mere abrupt their releac'. sucli Hexuie, that they exertccas eralilfz ferce in kicking the dust and dirt cvei adjacent. edge ofthe f` Mocem in moving the device over a spougy Surface. suc-l1 as acarpet7 rug 0r a garment., oe-til ei the clliccs just stated areattained in prcxif mate proportion to the degree ef pressure exertedupon the back ot' the casing. I limi, also, that in this connectionthere is advantage iu using a single lust pan, lcv-,ated to the rear ofthe brush, reckoned according to the general direction` of travel oftile sweeper over the surface to be cleaned. That te Say, find thatthere advantage in having the front portion oi' the casing open, or atleast in having no obstruction, carried by the Casing, in front 0i' thebrush. This arrangement enables the l. tilted slightly, if .esile, in e(lust in ma); sometiries mere ietfoi'aiele positien Speci-:atieu 0iLettsfs Rate eet Helmel tg get eut ef es the practical advantagescapable of removing and collecting iall articles from the fabric. r .ieolf my invention is Weil aapteof for the remove g f dirt, dust and othersimilar objecionaiile from .any surface, whether of soit surfaces suchas e woven fabric, or of baril surfaces such asphalt, paven'ieiits. etc.

in the accemyuiayiug drawings, I illustrate one iom el my device asapplied to the remo-:al of crumbs, clust and other loose material from etable-cloth, but I do not limit self to this particular use for myinvention.

Figure iilustrates an end View of one form of my device, partly brekenaway to slicvv the duetretaining receptacle. Fig. 2 ,lusates acress-sectien through the line Y et Fig. l. also partly breken away.

A is a easing, the. top portion C exteuelieg; above and over therevoluble brush B and being 'nent forward so as to form. the base plate.1li the oase plate being extended. werd te rel 1e revelubie brush unt-ilely approae. .ug the bristles thereof, lien being extened backward andupormin tile front edge E of the dust- Y neptacle L. The sides K. K areflied to, or: are extensions of, the top C. ami are further attached tothe iii such a iiiai'mei that the forward ef the lirvsli i5 will beexposed and The ,rush B comprises misil-- imt bristl i, attached to edouble twisted wire core G supported by and revolulsle upcu the two emibearings F. F.

il is a knol', attached to the top of the casing and so situated as tocause a uniform firm preseure of the base D upon the ,surface over whichthe device is passed. The brush B so situated as regards the base i?.that lie bristles will press upon the sur faee S over which the deviceis passed, and will revolve *when the sweeper is given a forwarlmovement.

` fn the above description it is evident of the brush` will pressforming a curve, as shown when the device is pushed m of the brush uponthe -surfaee will cause it to revolve, and that this with more or lessviolenee and torce.

lt is thus seen, that the dust, removing ability ol' the device does notdepend upon the action of a rapidly'revolving brush which pulls or dragsthe dirt from the surface, bui is caused b v the snapping haelt'- wai'dof the bristles olI the brush, which receives itsaevolving motiondirectly from the surface over which it passes, and which motion is notgreater than that ot' the device itself.

The forward portion ot the brush is exposed to allow it to collect largepieces of material, and the lower portion is exposed to allow thebristles to come into contact with the surface o\er which the device isnassed.

'lhe complete exposure ol' the brush. at, the lower tront end of theeasing, also enables the Hexure 0f the bristles to be increased, at thewill of the operator, by slightly tilting the rear end of the easingupward, or even by applying a little more pressure upon the front end otthe easing than upon the, rear end thereof. 'lhis is especially truewhere the surface to he cleaned is soft or spongy, as for instance acarpet, a rug or a. garment.

The collected dirt ma)v be readily removed by reversing the position otthe sweeper, allowing it to fall ont through the space between the brushand the top part of the Casin".

I do not limit myself to the particular form, shape, size or arrangementolf the va l'ious elements described abovel all ot' whieh eair be variedwithout going lieif'on'd the scope of my invention as described andclaimed.

Having thus described my invention, what 1. In a device of the characterdescribed, the combination ot a easing provided with a journaled in saideasing' that a pressure upon the casing will l'oree' both dust pan andbrush into closer engagement with the. surface over which it is passed.said brush having its axis olI rotation iinn'iovable relativetv to saiddust pan and located adjacent one edge thereol. said brush beingprovided with bristles extending slightly away l'roin `said casing inorder to engagelhe surl'ace to be cleaned. and thus to become llexed andreleased. throwing the dust baclt'ward into the dusl pan` and also toturn said brush hv direct pressure ol' .said bristles upon .saidsui-lace to he cleaned.

2. A\ device ol' the character described, comprising a casing providedwith. a dust. pan and adapted to glide o\ 'er a surl'ace to be cleaned.a revolnble brush carried b v said easing and actuated hv directpressure oll said brush upon said surlaee to he cleaned, the axis ollrotation oll said brush being iinmovable relativelv to said dust pan.I'oi the purpose ot' enabling pressure applied to the bacl( ot. saidcasing. to l'orce both said dust pan and said brush into closerengagement with said surl'ace to be cleaned` the, liiush possessing.sullicient i'esilienc to throw the dust. bacltward into said dust pan.

2i. ln a device of the character described, the combinationol. a casingprovided with a dust pan, a revol`uhle. brush located upon oney side ol'said dust pan. ainl actuated solely b v its direct drag upon thesurl'aee to be cleaned, said brush being exposed upon its side oppositesaid dust pan` and a pair ot" hearings secured rigidlv to said casingand supporting' said revoluble brush, t'or the purpose of rendering theaxis ot' rotation ot said brush immovable relativelv to said easing andsaid dust pan and so situ-I ated that a pressure upon the casing willforce. both the dust pan and the brush into closer engagement `with the.surl'ace over which it is passed, the brush possessing sut'- fieientresiliency to tihijow ;t.l ie dust haeltward into the dust pan.
